Abstract
Young mink kits (n=8) were vaccinated with DNA plasmids encoding the viral haemagglutinin protein (H) of a vaccine strain of Canine distemper virus (CDV). Virus neutralising (VN) antibodies were induced after 2 immunisations and after the third immunisation all kits had high VN antibody titres. The VN antibody titres remained high for more than 4 months and the mink were protected against viraemia, lymphopenia, clinical disease and changes in the percentage of IFN-gamma producing peripheral blood leucocytes after challenge inoculation with a recent wild type strain of CDV. Essentially, these results demonstrate that early life DNA vaccination with the H gene of a CDV vaccine strain induced robust protective immunity against a recent wild type CDV.
